SPL is mainly known for the development of highly specialized audio-tools.
Our philosophy, ”one product for one task”, is aimed at f ast and simple operation in conjunction with high processing quality to ensure an excellent musical
performance.
With Track One SPL have produced a complete channel strip which for the
greater part is based on the processing concepts already successfully realized
in other products. The very complex task of a channel strip profits particularly from the innovative techniques that have always allowed the operation
of SPL equipment to be efficient and objective. The ususal recording day is
to a high degree determined by a series of opposing time limits – the ”highly
paid” singer/speaker desires a quick recording; however, if technical preparation takes a long time because of unsuitable equipment, time will be lost,
increasing the costs and souring the working environment. The Track One
in all cases however allows fast production without any loss of professional
precision and diligence.
The Track One consists of pre-amplifiers optimized for all kinds of microphones and instruments, SPL‘s acclaimed De-Esser, a compressor/limiter that
can be linked with the compressor of a second unit for stereo operation, an
equalizer (EQ) section for sound corrections or creations and an output stage
for perfectly feeding following units. A central display shows metering for
output level and gain reduction and all other status LEDs.
The Track One is a channel strip that excels primarily in two aspects: it is disarmingly easy to use and offers outstanding sound qualities.
This concept is ideally suited for alle kinds of vocal and instrument recordings in studio, broadcast or live applications as well as for „one man show“
entertainment.
The controls are reduced to the necessary basics to ensure highest userfriendliness. Therefore, working with the Track One can be dramatically timesaving which is most important especially in live situations.
Due to its excellent sound quality the Track One is a highly recommended
alternative to built-in console pre-amps and processing tools. All the modules
are immediately at hand for fast interactions. Recording a voice and providing
clarity, detail and intelligibility is a question of seconds.
Optionally the Track One can be equipped with a 24 bit/96 kHz Ad converter
for direct digital recording. An additional connector allows to insert a second
signal - if for example two Track Ones are used to process stereo material,
only one converter is needed.
The second option is a Lundahl tr ansfor mer input stage. These transfor mers
already amplif y the microphone signals by factor 5 – the preamps are relieved
by this factor, which improves noise values and linearity of the amplification
in the high frequency spectrum.
Introduction

A special feature of the printed circuitry layout is the central star ground
wiring scheme: Disturbing influences that could affect the ground paths are
minimized in that the audio-ground is separated from the ground of the
remaining equipment. This leads, in the truest sense of the word ”clean”, to
considerably improved tonal quality. The scatter free toroidal transformer,
manufactured to SPL tolerances, supplies the equipment with the necessary
voltages and forms the basis for a clean electrical supply to all parts of the
circuitry.
Carefully select a place for setting up the Track One. The unit should be
situated away from heat sources and direct sunlight. Avoid installation in environments exposed to vibrations, dust, heat, cold or moisture. Keep the unit
away from transformers or motors or any other unit that could generate large
variations in power supply or cause electrical interferences. Do not install the
unit in proximity to power amplifiers or digital processors. You may consider
placing it in a rack containing other analog gear. Such placement can prevent
interference from Word Clock, Smpte, MIDI, etc.
• Do not open the case. You may risk electric shock and may damage your
equipment.
• Leave repairs and maintenance to a qualified service technician. Should
foreign objects fall inside the case, contact your authorized dealer or support
person.
• To avoid electric shock or fire hazards do not expose your unit to rain or
dampness.
• In case of lightning unplug the unit. Please unplug the cable by pulling on
the plug only; never pull on the cable.
• Never force a switch or knob.
• To clean the case use a lint-free cloth. Avoid cleaning agents as they may
damage the chassis. Manufactured in standard 19“ EIA format, it utilises
two rack units.
• Please support the back of the unit whenever it is being mounted into a
19 inch rack (especially important when touring).
